Dear professionals,
I'm facing next problem: when try to execute SQL query inside SQL Developer it raises error: ORA-12705 Cannot access NLS data files or invalid environment specified.
Error appeared after I changed some region settings in Windows 10 (unfortunately, I cannot remember which one). Exactly the same query executed smoothly before that change in OS.
I tried to alter sqldeveloper.conf file according to this but no success.
AddVMOption -Duser.language=en
AddVMOption -Duser.region=US
AddVMOption -Duser.country=en
I'm using Sql Developer version 20.4.0.379 and 21.2.1.
Thanks in advance
